Coagulation And Flocculation in Water Treatment Explained

Coagulation is the process of adding chemicals to water, causing them to bind together and form ¡®flocs¡¯. Flocculation is the process of adding flocculant to water, which further encourages floc formation and increases the floc sizes, making them easier to remove.

Common chemicals used in this step include specific types of salts, aluminum, or iron. Flocculation Flocculation follows the coagulation step. Flocculation is the gentle mixing of the water to form larger, heavier particles called flocs. Often, water treatment plants will add additional chemicals during this step to help the flocs form.

The first two steps include the processes of coagulation and flocculation. In this process, colloidal particles are destabilized to gather all the suspended material together. They can also be referred to as nonstable solids. This process increases particle sizes which assists in removal during the filter process.

Chemicals (coagulants) are added to the water to bring the nonsettling particles together into larger, heavier masses of solids called floc. Aluminum sulfate ( alum) is the most common coagulant used for water purification. Other chemicals, such as ferric sulfate or sodium aluminate, may also be used.

COAGULATION AND FLOCCULATION - MRWA

Coagulant chemicals with charges opposite those of the suspended solids are added to the water to neutralize the negative charges on non-settlable solids (such as clay and color-producing organic substances). Once the charge is neutralized, the small suspended particles are capable of sticking together.

flocculation - wikipedia

Flocculation - Wikipedia

Surface chemistry In colloid chemistry, flocculation refers to the process by which fine particulates are caused to clump together into a floc. The floc may then float to the top of the liquid (creaming), settle to the bottom of the liquid ( sedimentation ), or be readily filtered from the liquid.

Coagulation (water treatment) - Wikipedia

Coagulation is a chemical process that involves neutralization of charge whereas flocculation is a physical process and does not involve neutralization of charge. The coagulation-flocculation process can be used as a preliminary or intermediary step between other water or wastewater treatment processes like filtration and sedimentation .

Polymers for Coagulation and Flocculation in Water Treatment

The classification of the synthetic organic polymers used in water and wastewater treatment operations is based on the ionic charge present, e.g. cationic, anionic and non-ionic polyelectrolytes. Cationic polyelectrolytes formed the largest number of polymeric coagulants that have been used in CF operations.
